2、环境部署
2.1 MySQL8.0.20 实例部署，以tidb60主机上为例。
mkdir -p /home/mysql_cluster/my3366/{socket,data,logs,dump_dir}
cd /home/mysql_cluster
chown -R mysql:mysql my3366
/usr/local/mysql8020/bin/mysqld --defaults-file=/home/mysql_cluster/my3366/my3366.cnf --initialize
nohup /usr/local/mysql8020/bin/mysqld_safe --defaults-file=/home/mysql_cluster/my3366/my3366.cnf --user=mysql &
/usr/local/mysql8020/bin/mysql -S /home/mysql_cluster/my3366/socket/mysql3366.sock -uroot -p
create user dba@‘%‘ identified WITH mysql_native_password by ‘dba‘;
grant all on *.* to dba@‘%‘ with grant option;

2.2 配置检查
在tidb63主机上部署mysqlshell，下载后解压，配置环境变量即可使用，部署路径跟进实际环境即可。
